O you who believe! when you rise up to prayer, wash your faces and your hands as far as the elbows, and wipe your heads and your feet to the ankles; and if you are under an obligation to perform a total ablution, then wash (yourselves) and if you are sick or on a journey, or one of you come from the privy, or you have touched the women, and you cannot find water, betake yourselves to pure earth and wipe your faces and your hands therewith, Allah does not desire to put on you any difficulty, but He wishes to purify you and that He may complete His favor on you, so that you may be grateful.

Then I will certainly come to them from before them and from behind them, and from their right-hand side and from their left-hand side; and Thou shalt not find most of them thankful.

That they may eat of the fruit thereof, and their hands did not make it; will they not then be grateful?
